If your GPS updates every 5 minutes, then that’s a $GPGGA and possibly a $GPRMC sentence every 300 seconds.
In general, each of these sentences is under 80 characters (usually around 64 characters IIRC). Conservatively using 80 characters, we have 80*8=640 bits every 300 seconds.
This leaves 1,572,224 bits per second on a T1 for protocol overhead.
OTOH, if you’re talking about the SWIP template size (reassign simple is all that this really calls for), then that’s a bit larger, weighing in at 463*8 = 3,704 bits without any data added to the basic template. Let’s assume another an average of 40 characters (probably closer to 20, but let’s again be conservative) for each of the 12 fields giving us an additional 480*8=3,804 bits for a total of 7,508 bits. Adding EMAIL message size overhead and TCP/IP overhead, let’s call it an even 16Kbits per SWIP. (that’s pretty high overhead, I think) At that rate (16kbb per 300 seconds, A T1 requirement means you need to support 28,800 busses in your system.
As such, 1,000 busses or less actually fit on a DS0 with room to spare.
> Right now, all 500+ busses use a static IPv4 address, that is assigned by the Major wireless provider. They are NOT in a block reserved for us. They are scattered around several blocks of addresses of the provider, some of which they appear to be leasing from another party, and those SWIP records list the leasing company. None of them have a SWIP to us, our provider has to forward the reports to us, sometimes thru the leasing co.
While there may be people willing to SWIP GPS coordinates, I would argue this is the exception rather than the rule and constantly updating SWIP to reflect the location of a mobile element rather than simply SWIPing it to a headquarters location is illogical in the extreme.
> As we move to v6, I am hoping the policy will change from 100% SWIP to a level not requiring it. This is because our provider insists the current ARIN rule requires a street address for each bus. I think I will point them to the thread that states the site address is not required in SWIP, and we can use the ADMIN address, or better yet wait for the policy to change and let them forward reports just like they do in v4. In any case, my guess is that nearly no abuse will happen on v6 for lack of customer abuse, and we will continue to receive a couple of reports a month on the new contract dynamic addresses, if they at the provider can even figure out who to send them to, as in the future the addresses for v4 might be CGnat, and they would have to figure out who did it.
The provider is mistaken. The current ARIN rule requires a street address for each customer delegation in excess of a /64. If he delegates a /48 to the bus company (or even a /32 or a /24 or whatever), then he only needs to SWIP the address of the bus company on that particular block and he has fulfilled his ARIN obligations. (This is my personal opinion and not an official statement from ARIN staff or the AC, however, I’m sure one of those entities will correct me quickly and publicly if I am wrong).
I’ve worked for and with a number of ISPs and end users and dealt with many ARIN allocations and assignments as well as many reallocations and reassignments to downstream customers. I assure you that SWIPing individual busses even if each bus got an IPv4 /24 would be considered illogical by virtually anyone involved in the process and that SWIPing an aggregate block to the bus company would make much more sense.
If each bus gets a random IPv6 static assignment individually and they can’t be aggregated, then, they would have to be SWIP’d individually, but they could still be SWIP’d to the address and name of the bus company without requiring the current location of the individual bus in question.
